Arguments

result

Returned with the arc tangent of operand. (a8)

operand

The radian value whose arc tangent will be returned. (a8)

Discussion

The FP_ARCTAN subroutine returns the arc tangent of a floating‑point number.

The following operation is performed:

result = arctan(operand)

Result and operand are native floating‑point numbers represented as a8 variables.
